Optiphen Plus (Preservative/ Pengawet)

Tuesday, 1 March 2016

We in Soaplab just recieved a new preservative called the Optiphen Plus. If you are one of those who loves to read tutorials on handmade products, im preety sure you would have encountered this preservatives.

Because of sorbic acid, this ingredient is more suitable for product with low ph (slightly acidic), though there are studies that show its stable in pH 8 as well. However to be on the safe side, stick to ph 7 and below when using this preservative. So what product would that be. Basically anything and everything besides soap as our handmade soaps are mostly with ph 8 and above. Liquid soap it depends. If you had diluted it and reduced the ph to 7, then this preservative can be used for it too.

Can i use antioxidants like vitamin E and grapeseed oil as preservatives?

Tak bolehkah saya mengunakkan antioxidant seperti vitamin e dan grapeseed oil sebagai pengawet?No. Anti oxidants are only there to stop rancidity of oils. To date there isnt any study to show that it helps in killing those bacteria and fungus. Read this previous post to find out more about how antioxidant works.

If i were to use optiphen plus, how much to use? Berapa nak guna?

Usage rate is 0.75% to 1.5%

hi..i want to do lipbalm using shea butter..beeswax..vitamin e and essential oil..do i need to put preservative so that it cam be keep at long time?because i want to commercial my product but at the same time i want it 100% natural without chemical & preservative.

Hi @Amny syaf ' you dont need to use preservative for ur lipbalm as its all oil based item and there is no water. The best way to keep it longer shelf life would be to use oils with longer expiry like shea butter and coconut or olive oil, and put in 1% vit e as antioxidant to prevent the oils from becoming rancid fast:-)
